[0004] Based on the search, we know that the existing technology still has shortcomings:

[0005] Traditional steel coil elevators have a small lifting stroke and low carrying capacity. Therefore, a steel coil elevator is needed to improve the above-mentioned shortcomings. Summary of the invention

[0006] The main purpose of the present invention is to provide a steel coil elevator.

[0007] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0008] A steel coil elevator comprises a lifting structure for transporting steel coils;

[0009] The lifting structure is mainly composed of a frame, a car, a saddle, a lifting guide 1, a lifting guide 2, a lifting cylinder 1, a lifting cylinder 2 and a lifting cylinder 3;

[0010] Lifting cylinder three is fixed on the frame, the cylinder head on lifting cylinder three is connected to lifting guide two, lifting cylinder two is fixed on lifting guide two, the cylinder head of lifting guide two is connected to lifting guide one, lifting cylinder one is fixed on lifting guide one, the cylinder head of lifting cylinder one is connected to the car, the saddle is fixed on the frame, and the frame, lifting guide one and lifting guide two can all be stably lifted and lowered on the frame.

[0011] Preferably, the frame is a cross-spliced ​​fixed structure.

[0012] Preferably, lifting cylinder three pushes lifting guide two to the limit of the cylinder.

[0017] Preferably, the car is connected in a lifting manner along a lifting guide 1 and a lifting guide 2 on the frame.

[0018] Beneficial technical effects of the present invention:

[0019] The steel coil elevator provided by the present invention has the following advantages:

[0020] 1. Deep digging foundation, three sets of cylinders provide power, the bottom of the cylinders are on the same horizontal line, saving civil engineering costs, and the cylinders provide reliable braking;

[0021] 2. Strong load-bearing capacity. The oil cylinder can generate a large thrust, which makes it very suitable for lifting equipment that carries heavy objects. The oil cylinder can provide enough power to lift or lower smoothly. Moreover, when the oil cylinder is under heavy load, its structure is relatively stable and will not be easily deformed or damaged like some other transmission mechanisms, which can ensure long-term and reliable operation;

[0022] 3. The structure is simple and reasonable, the lifting guide is stable and runs smoothly, and the movement of the oil cylinder is relatively stable. It realizes telescopic movement through the pressure transmission of hydraulic oil. This movement is relatively gentle and continuous. During the operation of the steel coil lifting elevator, the oil cylinder can make the car rise or fall smoothly without violent shaking or impact. This is very important for protecting the steel coil and other equipment in the elevator, because the steel coil is a kind of cargo that requires high stability in transportation. Any excessive shaking may cause displacement, collision or even damage of the steel coil;

[0023] 4. A limit pin is set when the lifting reaches the limit position to ensure that the steel coil can be stably transported at the lifting limit position;

[0024] 5. Precise control can be achieved. The oil cylinder can accurately control the lifting speed by adjusting the flow of hydraulic oil. In different working scenarios, such as when loading steel coils, a steady speed is required, while in no-load or emergency situations, a faster speed may be required. By installing corresponding hydraulic valves and other control components, the speed of the oil cylinder can be easily adjusted;

[0025] 6. High reliability. The cylinder has strong adaptability to the working environment. Even under relatively harsh conditions, the cylinder can maintain relatively stable operation and reduce the occurrence rate of failures caused by environmental factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The frame 1 is a cross-jointed fixed structure.

[0035] The lifting cylinder 3 8 pushes the lifting guide 2 5 to the limit of the cylinder.

[0036] The lifting cylinder 2 7 pushes the lifting guide 1 4 to the limit of the cylinder.

[0037] The lifting cylinder 1 6 pushes the car 2 to the limit position of the cylinder.

[0038] The car 2, the lifting guide 1 4 and the lifting guide 2 5 return to their initial positions.

[0039] The bottoms of the lifting cylinder 1 6 , the lifting cylinder 2 7 and the lifting cylinder 3 8 are at the same level.

[0040] The car 2 is connected to be lifted along the lifting guide 1 4 and the lifting guide 2 5 on the frame 1 .

[0041] like Figure 1 - Figure 3 As shown, the working process of a steel coil elevator provided by this embodiment is as follows: during operation, the steel coil is sent to the saddle 3 in the car 2, the unit sends a signal, and after confirming safety, the lifting cylinder three 8 pushes the lifting guide two 5 to the limit position of the cylinder, the lifting cylinder two 7 pushes the lifting guide one 4 to the limit position of the cylinder, and the lifting cylinder one 6 pushes the car 2 to the limit position of the cylinder, and the steel coil reaches the upper limit position of the elevator. After the steel coil is transported out at the upper limit position, each cylinder retracts, and the car 2, lifting guide one 4, and lifting guide two 5 return to the initial position, waiting for the next coil transportation, and the operation is cyclical.

[0042] Example

[0043] like Figure 1 - Figure 3 As shown, the steel coil lifting elevator is mainly composed of a frame 1, a car 2, a saddle 3, a lifting guide 1 4, a lifting guide 2 5, a lifting cylinder 1 6, a lifting cylinder 2 7, and a lifting cylinder 3 8, wherein the lifting cylinder 3 8 is fixed on the frame 1, the cylinder head is connected to the lifting guide 2 5, the lifting cylinder 2 7 is fixed to the lifting guide 2 5, the cylinder head is connected to the lifting guide 1 4, the lifting cylinder 1 6 is fixed to the lifting guide 1 4, the cylinder head is connected to the car 2, and the saddle 3 is fixed to the car 1, and the car 1, the lifting guide 1 4, and the lifting guide 2 5 can all be stably lifted and lowered on the frame 1;

[0044] During operation, the steel coil is sent to the saddle 3 in the car 2, the unit sends a signal, and after confirming safety, the lifting cylinder 3 8 pushes the lifting guide 2 5 to the limit position of the cylinder, the lifting cylinder 2 7 pushes the lifting guide 1 4 to the limit position of the cylinder, and the lifting cylinder 1 6 pushes the car 2 to the limit position of the cylinder, and the steel coil reaches the upper limit position of the elevator.

The three groups of cylinders provide power, and the bottom of the cylinders are on the same horizontal line, saving civil engineering costs. The cylinders provide reliable braking and have strong bearing capacity. The cylinders can generate a large thrust, which makes it very suitable for lifting equipment that carries heavy objects. The cylinders can provide enough power to lift or lower smoothly, and when the cylinders are under heavy load, their structure is relatively stable, and they will not be easily deformed or damaged like some other transmission mechanisms, which can ensure long-term and reliable operation, simple and reasonable structure, stable and smooth operation of the lifting guide, and relatively smooth movement of the cylinders. It achieves telescopic movement through the pressure transmission of hydraulic oil. This movement is relatively gentle and continuous. During the operation of the steel coil lifting elevator, the cylinder can make the car rise or fall smoothly without severe shaking or impact. This is crucial to protecting the steel coil and other equipment in the elevator, because the steel coil is a kind of cargo that requires high transportation stability. Any excessive shaking may cause the steel coil to shift, collide or even be damaged. A limit pin is set when lifting to the limit position to ensure that the steel coil can be stably transported at the lifting limit position, and precise control can be achieved. The cylinder can accurately control the lifting speed by adjusting the flow of hydraulic oil. In different working scenarios, such as when loading steel coils, a steady speed is required, while a faster speed may be required in no-load or emergency situations. By installing corresponding hydraulic valves and other control components, the cylinder speed can be easily adjusted. It has high reliability and a strong adaptability to the working environment. Even under harsh conditions, the cylinder can maintain relatively stable operation, reducing the occurrence of failures caused by environmental factors.
